Anti-tipping half-portal cantilever crane with reaction wheel type running trolley

Abstract

This application discloses a semi-gantry cantilever crane with anti-roller running trolley and anti-tipping, which includes a half-gantry composed of an end beam, two main beams, and outrigger frames; and hanging cables; the running trolley is connected to the track above the main girder; the end girder is composed of a balanced end girder and a connecting rod; Car driving device and passive wheel set; horizontal wheel devices are installed at both ends of the end beam; steel rails are installed on the outside of the two main beams; both sides of the running trolley are connected with anti-rolling device, and the anti-rolling device is lapped on the rail to run; on the running trolley A rotating mechanism is provided; the lower end of the boom shaft in the rotating mechanism is connected with the cantilever component through a flat key and a locknut; the cantilever beam in the cantilever component is connected with an electric hoist; the cantilever beam is placed under the two main beams and can rotate.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a semi-gantry cantilever crane with anti-roller running trolley and anti-tipping. Background technique [0002] Existing bridge cranes are used in enterprise workshops. Some workshops are equipped with many machine tools for processing and production. Products and raw materials need to be transported to the next workshop or other departments in real time; the hooks of the cranes in the workshop are hung from the trolley. For hoisting goods, the trolley can only run back and forth along the double girders of the crane, and the crane can only run back and forth along the cart rails on the cross columns on both sides of the workshop, so that the range of goods that the crane hook can lift is within the distance between the two cart rails in the workshop. Within the plane surrounded by the two ends, when the goods at the edge of the plane need to be hoisted, the hook will be pulled ob...

Problems solved by technology

[0002] Existing bridge cranes are used in enterprise workshops. Some workshops are equipped with many machine tools for processing and production. Products and raw materials need to be transported to the next workshop or other departments in real time; the hooks of the cranes in the workshop are hung from the trolley. For hoisting goods, the trolley can only run back and forth along the double girders of the crane, and the crane can only run back and forth along the cart rails on the cross columns on both sides of the workshop, so that the range of goods that the crane hook can lift is within the distance between the two cart rails in the workshop. Within the plane surrounded by the two ends, when the goods at the edge of the plane need to be hoisted, the hook will be pulled obliquely, and the items farther away from this plane (such as outside the workshop door, outside the span) cannot be hoisted. At this time, it can only be transferred with the help of other transportation equipment. Usually, the car drives into the workshop to lift the goods under the hook. Go to the hook to hand over the goods, and some set up a special cantilever crane at the workshop door (or workshop aisle) to transfer and dispatch the goods outside the workshop, first hoist the goods into the place where the crane hook of the workshop can reach , and then the cargo is hoisted by the crane to other stations in the workshop. The existing bridge crane used in this working condition cannot directly transfer the cargo with the workshop next door, and must use other transportation equipment to schedule operations, which brings considerable inconvenience. It also wastes manpower and material resources
